Unit Weight of Construction Materials

Unit weight of Concrete (PCC) – 2300 Kg/m3

Unit weight of Concrete (RCC) – 2400 Kg/m3

We may hear that the above sentence a lot of time !. not only concrete like Steel, Sand, Blue metal. So here we discuss what is the unit of material & why it is required?

What is Unit Weight?

Unit weight of the material is simply defined as Mass per Volume (M/V) and also it is called as Unit Weight of material. For better understanding, If a Steel weight 100 Kg (M) then the steel was immersed in water & weighed again (V). Another name of unit weight is called Density.

Density = M/V

There are so many materials were using in the construction industry. We have to know the unit weight of the material to estimate the quantity of material.

Here we list out the Density values for some material & if anything we missed out let us know to add.
